Glint360K contains ** 17091657 ** images of ** 360232 ** individuals. By employing the Patial FC training strategy, baseline models trained on Glint360K can easily achieve state-of-the-art performance. Detailed evaluation results on the large-scale test set (e.g. IFRT, IJB-C and Megaface) are as follows: # 1. Evaluation on IFRT ** r ** denotes the sampling rate of negative class centers. | Backbone | Dataset | African | Caucasian | Indian | Asian | ALL | | —————— | —————- | ——- | ——- | ——— | ——- | ——- | | R50 | MS1M-V3 | 76.24 | 86.21 | 84.44 | 37.43 | 71.02 | | R124 | MS1M-V3 | 81.08 | 89.06 | 87.53 | 38.40 | 74.76 |

Anxiety involves anticipating aversive outcomes and can impair neurocognitive processes,
such as the ability to recall faces encoded during the anxious state. It is important to delineate
and determine the replicability of these effects using induced anxiety in the general
population, to understand its manifestation in anxiety disorders. This study therefore aimed to
replicate prior research on the distinct impacts of threat-of-shock-induced anxiety on the
encoding and recognition stage of emotional face processing, in a large asymptomatic sample
(n=92). We successfully replicated previous results demonstrating impaired recognition of
faces encoded under threat-of-shock. This was supported by a meta- and mega-analysis
across three independent studies using the same paradigm (n=211). Underlying this, a whole brain fMRI analysis revealed enhanced activation in the posterior cingulate cortex (PCC),
alongside previously seen activity in the anterior cingulate cortex (ACC) when combined in a
mega-analysis with the fMRI findings we aimed to replicate. We further found replications of
hippocampus activation when the retrieval and encoding states were congruent. Our results
support the notion that anxiety disrupts face recognition, potentially due to attentional
demands of anxious arousal competing with affective stimuli processing during encoding and
suggest that regions of the cingulate cortex play pivotal roles in this.
